Leading Ladies - Heidi Klum

Like fashion, in the sustainability world it seems that you're either in or you out...you get it or you don't. Who better to bring more people 'in' to the sustainability movement than a supermodel. Heidi Klum has done just that. Heidi often speaks publically about her concern for the environment, but she also walks her talk. She has frequently brought social and environmental awareness to the designer challenges on Project Runway and most recently she worked with Billie Jean King to design an eco-friendly t-shirt for the 2008 US Open. She's an avid social activist too, working on international issues such as HIV/AIDS in Africa, UNICEF, and the Red Cross.
